Quick Verdict
The enclosed self design is the whole pitch here: a sealed 90L globe that keeps 98% of kicked litter inside and runs at 40dB. No subscription, three safety sensors, and the app is optional. It pays off in a multi-cat house where you’re scooping twice daily; skip it for a single quiet apartment with one tidy cat.
Buy if you:
- Run a multi-cat household and are tired of scooping twice a day
- Have a shy rescue or former stray that avoids open boxes
- Own a big cat (Maine Coon, Ragdoll) up to 33 lbs
- Want app tracking without paying a monthly fee
Skip if you:
- Don’t have floor space for a full 90L globe (it’s big and it stays put)
- Have a kitten under the weight range the sensors are tuned for
- Want a simple manual box and don’t care about app notifications

The Sealed Globe Is the Point of an Enclosed Self Cleaning Litter Box
Litter scatter is the problem this thing was built to kill. As an OT I spend my days thinking about how a device changes a daily task, and cleaning up litter three feet from the box twice a day is exactly the kind of small repeated chore that wears people down. The Greesum enclosed self cleaning litter box goes at that with a sealed 90-liter globe that keeps 98% of kicked litter inside. If you want to check current pricing, you can see it here on Amazon.
The enclosed part isn’t just about your floors. A closed globe gives a cat the private, dark corner they instinctively look for, which matters more than most people realize for anxious cats.
What You’re Getting Inside the Box
90 liters is a lot of litter box. This is an XL unit rated for cats up to 33 lbs, so Maine Coons and Ragdolls are on the table, not just average house cats. The waste drawer is a sealed 6.5L bin that Greesum says holds about 7 days of waste for two cats before it needs a bag swap.
40dB and Three Sensors Doing the Safety Work
40 decibels is quieter than a library whisper, and that number matters. Skittish cats bolt at grinding motors, so a near-silent cleaning cycle is a big deal for the exact anxious cats this box is aimed at. Greesum leans on three safety systems: an infrared sensor that catches your cat entering and pauses the cycle, a microwave radar that stops motion the instant a cat touches the entrance, and a living-creature radar that scans inside the drum and locks rotation if it senses anything alive. Three independent layers is more redundancy than a lot of automatic boxes bother with.
The infrared sensor pulls double duty too, firing an alert when the waste drawer fills up. That feature turns this from a gadget into something that fits a real routine: you know when your cat used it and when the bag needs changing.
The App Is Free, and It Doesn’t Hold You Hostage
No subscription. That’s the line I’d underline. You get Auto, Scheduled, and Manual modes over 2.4GHz WiFi, plus usage tracking and full-drawer push notifications, all included for the life of the device. Litter-Robot charges $4.99/month just to keep insights unlocked. Greesum bundles remote cleaning, scheduling, and usage tracking into the purchase price and leaves it there permanently.
And if you’re the type who doesn’t want a litter box on your WiFi, the control panel on the unit works on its own. No internet, no problem. That’s a nice bit of flexibility for people who don’t want another connected device in the house.
The Footprint Is the Trade-Off
90 liters takes up serious floor space. That’s the trade-off with a fully enclosed globe: to give a 33-lb cat room and hold a week of waste, the unit has to be physically large, and it’s not something you tuck discreetly into a small bathroom corner. If you live in a compact apartment, measure your spot before you commit.
The other thing worth knowing going in: those safety sensors are tuned for cats within the box’s weight range. A very small kitten may not reliably trip them, so if you’ve got a tiny young cat, hold off on the automatic cycles until they’ve grown into it. That’s not a defect, it’s just the physics of how the sensors work, but it’s the kind of detail the box copy doesn’t put front and center.

Who This Box Actually Fits
If you’re scooping for two or three cats, the math shifts fast: daily scooping seven days a week becomes one bag swap on Sunday. The 6.5L sealed drawer is what makes that work, and it’s the single biggest reason a multi-cat household feels this differently than a single-cat one.
It also fits the anxious-cat crowd. Shy rescues and former strays that refuse an exposed box often take to a private, enclosed globe, and the quiet motor means the cleaning cycle won’t scare them back off it. Big cats fit too, which is more than a lot of automatic boxes can say.
Enclosed Self Cleaning vs. a Basic Manual Box
A basic covered manual box wins on two things: it’s cheap and it’s small. If you have one tidy cat and don’t mind a daily scoop, you don’t need any of this. Where the Greesum pulls ahead is the daily labor and the tracking. You stop scooping, the litter stays contained, and the app tells you your cat’s bathroom patterns, which can be a genuine early warning if a cat’s habits change. That last part is real health value a manual box simply can’t give you.
The manual box also never needs WiFi, never needs a firmware update, and can’t break a motor. An automatic box is more moving parts, so it’s a durability bet against convenience. For a busy multi-cat home, I’d take the bet.
Advice Before You Buy
Assembly runs about 3 minutes, then plug in, add litter, and go. It ships with a litter mat and 30 waste bags, so you’re not hunting for accessories on day one. Start on Manual or Scheduled mode for the first week, let your cat form the habit of using the box before it ever moves on its own. A nervous cat that bolts from one surprise rotation may refuse the box entirely, and that’s a harder problem to fix than a slow introduction.
Pros
- Sealed 90L globe keeps 98% of litter contained, killing the twice-daily vacuum
- Runs at 40dB so skittish cats don’t bolt
- Three independent safety sensors for cats up to 33 lbs
- Free app with tracking and full-drawer alerts, no subscription ever
- Control panel works without WiFi if you don’t want it connected
Cons
- 90L means a large footprint that won’t tuck into a small space
- Sensors are tuned for grown cats, so very small kittens may not trip them reliably
- More moving parts than a manual box, so it’s a durability bet over time
Frequently Asked Questions
Does the Greesum litter box need WiFi to work?
No. The control panel on the unit runs the box independently without any internet. The 2.4GHz WiFi app adds remote cleaning, scheduling, and notifications, but it’s optional.
Is there a monthly subscription or hidden fee?
None. Every app feature, including usage tracking and push notifications, is included for the life of the device. No cloud fee, no paywall on the good features.
How big of a cat can use it?
Up to 33 lbs, which covers large breeds like Maine Coons and Ragdolls. The 90L globe gives them room to turn around, unlike smaller automatic boxes that cramp big cats.
How often do I have to empty the waste drawer?
The sealed 6.5L drawer holds roughly 7 days of waste for two cats. When it’s full the app pings you, and swapping the bag takes about 10 seconds.
Is it safe for multiple cats using it at once?
Yes, the three sensors are built for exactly this. Infrared catches a cat entering, microwave radar stops motion on contact, and the living-creature radar locks rotation if anything is inside the drum.
Will the cleaning cycle wake me or scare my cat at night?
Unlikely. At 40dB it’s quieter than a whisper, so a 3 AM cycle usually goes unnoticed by both you and a nervous cat. There are no sudden grinding noises.
What comes in the box, and how long is the warranty?
You get the unit, a litter mat, and 30 waste bags, with a 12-month warranty. Assembly takes about 3 minutes before you add litter and plug in.
Can I use my own litter and waste bags once the starter set runs out?
Yes, it uses standard clumping litter. Once the included 30 bags are gone you can restock with compatible liners rather than being locked into a proprietary consumable.
